Further, the upper surface 11 of the circuit substrate 1 includes a chip placing area 13, a first solder area 14, and a second solder area 15. The chip placing area 13 can be a solderless area.

For example, the image sensing chip 2 can be a complementary metal oxide semiconductor (CMOS) sensor or any sensor with an image capturing function, but the present disclosure is not limited thereto.

Therefore, the image sensing chip 2 can be electrically and respectively connected to the first solder area 14 and the second solder area 15 of the circuit substrate 1 through the first conductive area 24 and the second conductive area 25.

The image capturing module M further includes a filter element 3 disposed on the image sensing chip 2. For example, the filter element 3 can be directly disposed on the image sensing chip 2 by an adhesive (as shown in FIG. 1), or the filter element 3 can be disposed above the image sensing chip 2 by a plurality of pillars (not shown). In addition, the filter element 3 may be a coated glass or a non-coated glass, but the present disclosure is not limited thereto. Further, the lower surface 31 of the filter element 3 has a light transmitting area 32 and a connecting area 33 surrounding the light transmitting area 32, and the connecting area 33 of the filter element 3 corresponds to the carrier area 23 of the image sensing chip 2.

In summary, two sides of the circuit substrate 1 and the image sensing chip 2 can be electrically connected to each other by disposing the first solder area 14, the second solder area 15, the first conductive area 24 and the second conductive area 25. Therefore, the width or size in the horizontal direction of the other two sides of the circuit substrate 1 and the image sensing chip 2 can be reduced. That is, since the solder area and the conductive area can be omitted on the other two sides of the circuit substrate 1 and the image sensing chip 2, the width of the circuit substrate 1 and the image sensing chip 2 in the horizontal direction (X direction) can be reduced. Thereby, the size of the image sensing chip 2 in the horizontal direction is reduced.

For example, a plurality of first solder pads 141 may be disposed on the first solder area 14 of the circuit substrate 1, a plurality of second solder pads 151 may be disposed on the second solder area 15. In contrast, a plurality of first conductive parts 241 may be disposed on the first conductive area 24 of the image sensing chip 2 and a plurality of second conductive parts 251 may be disposed on the second conductive area 25. Therefore, the plurality of first conductive parts 241 of the image sensing chip 2 are electrically connected to the plurality of first solder pads 141 by respectively passing through the plurality of first conducting wires 51, and the plurality of second conductive parts 251 are electrically connected to the plurality of second solder pads 151 by respectively passing through a plurality of second conducting wires 52,.

The first side 131 of the chip placing area 13 is disposed opposite to the second side 132, and the third side 133 of the chip placing area 13 is disposed opposite to the fourth side 134. The first side 201 of the image sensing chip 2 is disposed opposite to the second side 202, and the third side 203 of the image sensing chip 2 is disposed opposite to the fourth side 204. The first side 231 of the carrier area 23 is disposed opposite to the second side 232, and the third side 233 of the carrier area 23 is disposed opposite to the fourth side 234.

The upper surface 21 of the image sensing chip 2 includes a third conductive area 26 connected between a fourth side 234 of the carrier area 23 and a fourth side 204 of the image sensing chip 2.

In conclusion, one of the beneficial effects of the present disclosure is that the image capturing module and the portable electronic device provided by the present disclosure can reduce the width or size of the image sensing chip in the horizontal direction by the technical features of “the upper surface 11 of the circuit substrate 1 including a chip placing area 13, a first solder area 14, and a second solder area 15; the chip placing area 13 being a solderless area; the first solder area 14 connected between a first side 131 of the chip placing area 13 and a first side 101 of the circuit substrate 1, the second solder area 15 connected between a second side 132 of the chip placing area 13 and a second side 102 of the circuit substrate 1, and a third side 133 of the chip placing area 13 connected to a third side 103 of the circuit substrate 1.”, “the upper surface 21 of the image sensing chip 2 including an image sensing area 22, a carrier area 23, a first conductive area 24, and a second conductive area 25; the first conductive area 24 connected between a first side 231 of the carrier area 23 and a first side 201 of the image sensing chip 2, the second conductive area 25 connected between a second side 232 of the carrier area 23 and a second side 202 of the image sensing chip 2, the carrier area 23 surrounding the image sensing area 22, and a third side 233 of the carrier area 23 connected to a third side 203 of the image sensing chip 2.”, “the lower surface 31 of the filter element 3 having a light transmitting area 32 and a connecting area 33 surrounding the light transmitting area 32.” and “the first conductive area 24 and the second conductive area 25 electrically and respectively connected to the first solder area 14 and the second solder area 15 of the circuit substrate 1, and the connecting area 33 of the filter element 3 corresponding to the carrier area 23 of the image sensing chip 2.”.

Another beneficial effect of the present disclosure is that, the image capturing module provided by the present disclosure can reduce the width or size of the image sensing chip in the horizontal direction by the technical features of “the upper surface 11 of the circuit substrate 1 including a chip placing area 13 and a first solder area 14 connected between a first side 131 of the chip placing area 13 and a first side 101 of the circuit substrate 1.”, “the upper surface 21 of the image sensing chip 2 including an image sensing area 22, a carrier area 23, and a first conductive area 24; the first conductive area 24 connected between a first side 231 of the carrier area 23 and a first side 201 of the image sensing chip 2, and the carrier area 23 surrounding the image sensing area 22.”, “the lower surface 31 of the filter element 3 having a light transmitting area 32 and a connecting area 33 surrounding the light transmitting area 32.” and “the first conductive area 24 of the image sensing chip 2 electrically connected to the first solder area 14 of the circuit substrate 1, and the connecting area 33 of the filter element 3 corresponding to the carrier area 23 of the image sensing chip 2.”.
